Christian Carlson was an 18-month-old toddler who died in Phoenix, Arizona, on November 15, 2012, after several days of vomiting, diarrhea, and a persistent fever described in records as gastritis.

Pinto told authorities she checked on Christian at about 4:00 a.m. on November 15 and thought he was all right, then found him unresponsive and not breathing around 6:00 a.m.; foam was noted at his mouth. He was taken by ambulance to Banner Thunderbird Medical Center, where staff recorded a very high body temperature of 106.3 degrees Fahrenheit. Despite treatment, Christian died. State child-fatality records characterize the death as a maltreatment fatality tied to neglect.

Phoenix Police and Arizona Child Protective Services investigated, removed the other children from the home, and offered services including substance-abuse treatment, supervised visitation, parent-aide assistance, and case management. Did anyone in Phoenix at that time have information about Christian’s illness or the household leading up to his death?
